per 'whatever the method'.
a simple search discovers that baptizo always meant immerse - fully cover. i was raised 110percent Lutheran, an they(mostly) claim otherwise, but they really squirm ackwardly when the truth is brought up in class, and they have to use 'man''s' reasoning to defend their practices.
later it was transliterated in english INSTEAD OF TRANSLATED.
that way, enough confusion resulted for whatever.
(sometime after 1400a.d. or so, someone claimed baptizo could mean other than immersed, but before that, it always meant immersed)
Last time I checked the Bible was before 1400.
Luke 11:38 NET.
(38) The Pharisee was astonished when he saw that Jesus did not first wash his hands before the meal.
Wash is the translation for baptizo in this instance it does not mean that the Pharisee was astonished because Jesus did not completely immerse himself in a ritual cleansing before the meal, he was surprised that Jesus did not cleanse his hands with the washing as prescribed by the Pharisees. In that you
poured at least the minimum amount of water over your hands. So there we have biblical support for one mode of baptism, pouring, commonly called effusion.
Then there is:
1 Corinthians 10:1-2 NET.
(1) For I do not want you to be unaware, brothers and sisters, that our fathers were all under the cloud and all passed through the sea,
(2) and all were baptized into Moses in the cloud and in the sea,
Where the entire nation of Israel (including infants) was baptised as they walked on dry land, the water was all around them, they were totally covered, but not immersed, that was the Egyptians who were immersed. This baptism would be most like sprinkling as any of you who have ever walked through a cloud (fog) can attest.
So there we have two examples, neither of which mean immersion. The one mode of baptism that cannot be shown for sure is immersion, but the symbolism is fine, immersion was an accepted form of ritual bathing or baptism and such that there is certainly no reason to think it is not okay. Of course if one follows the trinitarian formula, one would be immersed three times as you are baptised into each name. But most seem to skip that, we wouldn't want to get legalistic about it.
Now baptism was really quite well understood by the time John came along. The ritual baptism when people converted to Judaism was well known, the convert and his entire family would undergo ritual bathing and the men (any over 8 days old) would be circumcised. The baptism indicates that you are a follower of the beliefs into which you are baptised. Baptism is very strongly linked to being a disciple. This is why John complained at first when Jesus came to him to be baptised. It would be an indication that Jesus was a disciple of John. Of course Jesus' baptism was not John's baptism of repentance, but harkened back to the baptism of Aaron as he was installed as a high priest. Jesus as the new high priest needed to be baptised as part of his installation.
Aaron also figures into the practice of sprinkling for we see him and his sons cleansed by a baptism of blood whereby branches were dipped in the blood and then used to sprinkle them clean.
So multiple ways people were baptised in the Bible and all well established before the New Testament. Ritual washings (baptisms) by sprinkling, pouring, and even immersion were pretty common.
What had no basis in the culture was a man converting as an individual unless he was indeed an individual. If a man had said he wanted to convert, but refused to have his family convert as well, he would not have been accepted, how can a man covert to God, and leave his family outside the covenant? The man was very much the head of the household and if he converted the household was Jewish. The very idea that under the new covenant that now the household was no longer a part of it would have been totally foreign to their entire way of thinking and culture. It would have taken strong clear teachings to exclude such people as the children of believers from the new covenant. Of course if they were excluded, it would have been impossible to explain to Jews how the new covenant was superior to the old because their children were clearly included under the old.
So there, a little of the history of baptism mixed with some of the doctrine.
